Solve for y:
-8y - 4 < 6 + 9y

55% Answer Correctly

	y < \(\frac{1}{6}\)
	y < -4\(\frac{1}{2}\)
	y < -\(\frac{10}{17}\)
	y < \(\frac{1}{2}\)

Solution

To solve this equation, repeatedly do the same thing to both sides of the equation until the variable is isolated on one side of the < sign and the answer on the other.

-8y - 4 < 6 + 9y
-8y < 6 + 9y + 4
-8y - 9y < 6 + 4
-17y < 10
y < \( \frac{10}{-17} \)
y < -\(\frac{10}{17}\)

The dimensions of this cylinder are height (h) = 5 and radius (r) = 7. What is the surface area?

48% Answer Correctly

	28π
	72π
	256π
	168π

Solution

The surface area of a cylinder is 2πr² + 2πrh:

sa = 2πr² + 2πrh
sa = 2π(7²) + 2π(7 x 5)
sa = 2π(49) + 2π(35)
sa = (2 x 49)π + (2 x 35)π
sa = 98π + 70π
sa = 168π

If a = c = 6, b = d = 7, what is the area of this rectangle?

80% Answer Correctly

	72
	21
	63
	42

Solution

The area of a rectangle is equal to its length x width:

a = l x w
a = a x b
a = 6 x 7
a = 42

If BD = 27 and AD = 29, AB = ?

76% Answer Correctly

	9
	2
	14
	13

Solution

The entire length of this line is represented by AD which is AB + BD:

AD = AB + BD

Solving for AB:

AB = AD - BD
AB = 29 - 27
AB = 2

Order the following types of angle from least number of degrees to most number of degrees.

75% Answer Correctly

	acute, obtuse, right
	right, obtuse, acute
	acute, right, obtuse
	right, acute, obtuse

Solution

An acute angle measures less than 90°, a right angle measures 90°, and an obtuse angle measures more than 90°.
